Derivation is a linguistic and mathematical term describing the process of obtaining something from an original source. In linguistics, it refers to forming new words from existing ones by adding affixes, often changing word class or meaning (for example, forming a noun from a verb). In mathematics, it can denote the process of deriving a result, such as the derivative in calculus, from given functions or equations. In general usage, it expresses how something is traced back to, or developed from, an earlier form, principle, or source. The focus is always on systematic origin and development.
